Are you perfectionist when you make animation?
(In my case there's few types of situation:
When i'm perfectionist: this idea on animation is so stupid (soemtimes they aren't but i think they are). I won't do that. I should make better animation.
When i'm not perfectionist: hmm, this effect/animation doesn't look good, but Artem didn't care about that when he was making an animation on live so i won't change that, or i'll just make that faster, nobody will see this mistake.)
